$5\mathrm{.}16.$ Space station $*$

The space station orbits at a height of about $400km=4*{10}^{5}m,$ with a speed of about $7500\frac{m}{s}.$ What are the numerical values of the SR and GR time$-$dilation corrections, namely $\frac{v^2}{2}{c}^2$ and $g\frac{h}{c^2}?$ Which correction is larger, and by what factor?

Note: The $\frac{v^2}{2}{c}^2$ correction comes from applying the Taylor series $\sqrt[\phantom{2}]{1-x}$~~ $1-\frac{x}{2}$ to the SR time$-$dilation factor $\sqrt[\phantom{2}]{1-\frac{v^2}{c^2}}.$ The $g\frac{h}{c^2}$ correction isn't exact here, given the result in Problem $5\mathrm{.}3,$ but it's good enough for the present purpose.
